The month is thus and thus. (He then withdrew his thumb at the third time). He then said: Fast when you see it, and break your fast when you see it, and if the weather is cloudy calculate it (the months of Sha'ban and Shawwal) as thirty days.  

مسلم:١٠٨٠bحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو أُسَامَةَ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ

أَنَّ رَسُولَ اللَّهِ ﷺ ذَكَرَ رَمَضَانَ فَضَرَبَ بِيَدَيْهِ فَقَالَ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا ثُمَّ عَقَدَ إِبْهَامَهُ فِي الثَّالِثَةِ فَصُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ أُغْمِيَ عَلَيْكُمْ فَاقْدِرُوا لَهُ ثَلاَثِينَ

أَنَّ النَّبِيَّ ﷺ قَالَ صُومُوا الْهِلَالَ لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَأَكْمِلُوا الْعِدَّةَ ثَلَاثِينَ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَعَقَدَ

"الشَّهْرُ هكذا وهكذا وهكذا وعَقَدَ إِبْهَامَهُ في الثَّالِثَةِ، صُومُوا لِرُؤيَتِهِ وأفْطِرُوا لِرُؤيَتِهِ فإِنْ أُغْمِى عليكم فَاقْدُرُوا ثَلاثِينَ".
